"Hey I don't know You, But can I live here and have some cash?"

Yesterday someone I met via Halo started asking me a lot of questions, which is fine. People new to the college or role play generally do, and I love answering them and seeing interest in the college. She started out with basic questions now and then. "Do I get paid to be here?" "No, we are are a role play for the fun and love of interacting and acting with others, and we run on donations so we do not have any paying positions". A few hours later.. "Do I get free uniforms?" "No when we have uniforms, those sales are also a way to get the tier paid and keep the college going". Yet a little while later.. "Can one of the Dorm rooms be mine alone?" "No I'm sorry all parts of the school are for the entire community to share and use". A few minutes later... "Can I change my office?" "No one has there own office" "Can I change the nurses office" "No thats also part of the school intended for use by anyone and everyone". As the day goes by I get random im's like "Where are You?" "I'm working with a renter of mine". As the where are you im's come every so often I start to get annoyed, but hey I'm sick in real life so I think maybe it's just me being irritable.
Later tonight it got a little wierder. "Where are You". I'm in my house. "Can I see your house". I think what the hell, ok. "Sure" and I offer her a teleport. She lands, takes a look around. "Can I live here for a week?" "No I'm sorry this is my private space I use to work and build in". She says "ok". Keep in mind I barely know this girl. Then she changes her title tag to "Expecting Mommy". Then she says, "But I'm pregnant, Can I stay now". Again I say "No". She then tells me about her sl due date and baby shower. I tell her congrats and she says see you later and goes. I think Thank God that wierd situation is over. A few minutes after she tp's I get an im. "Can I borrow $640L?" Errrrrrr This one drives me nuts from strangers or people I barely, and I mean barely know. "No I'm sorry but lindens equal real money for me and this is how I support my family so I do not loan money to people I barely know". That's the last I have heard from her tonight.
What kind of behavior is ok within secondlife, and what are acceptable things to ask other players for and expect to get? I have been very blessed in secondlife, But I also feel I worked long and hard for what I have. If these questions came from a close friend, thats a different matter, and the answers most likely would of been of course you can stay here, or sure you can borrow $640L, but these questions came from a girl who my only contact with has been her asking me questions over the last day and a half. So just Errrrr!
